EDEN PRAIRIE — Minnesota Vikings coach Mike Zimmer says he has “no concern” about quarterback Teddy Bridgewater, after holding him out of the second preseason game as an injury precaution.

Zimmer said Saturday that Bridgewater could have played Thursday at Seattle, but the coach decided to keep him out. Zimmer refused to characterize Bridgewater’s condition, but ESPN.com reported Bridgewater has a sore shoulder.

Bridgewater practiced in full pads Saturday, but didn’t throw a pass. Backup Shaun Hill was given a rest, so Joel Stave took first-team snaps. With Taylor Heinicke on the non-football injury list, the Vikings signed Brad Sorenson for depth.

Sorenson, a fourth-year pro, has played with San Diego and Tennessee. He was a seventh-round draft pick in 2013 by the Chargers from Southern Utah, but has not appeared in a regular-season game.
